PETER ELLIS, OF CHRISTCHURCH, NEW ZEALAND.

GEAR FOR ROLLING-STOCK.

SPECIFICATION forming part of. Letters Patent No. 592,540, dated October26, 1897.

Application filed November 27, 1896. Serial No. 613,689. (No model.) i

To all whom it may concern:

Be it known that I, PETER ELLIS, mechanical engineer, a subject of theQueen of Great Britain ,and a resident of 71 Cathedral Square,Christchurch, in the provincial district of Canterbury, in the Colony ofNew Zealand, have invented new and useful Improvements in and Relatingto the Under Gear of Rolling- Stook, of which the following is aspecification.

This invention relates to the under gear of rollingstock and providesimprovements therein consisting of a bogie truck, in which only twowheels are employed upon'a single axle, the weight of the vehicle beingsupported in swing link-hangers which depend from an axle-box in whichthe axle is journaled at each end, the vehicle being pivoted to thebogie directly over the center of such axle.

The axle-box is tubular, an oil-chamber being thereby formed, and thebottom is made to slope from the middle toward 7 both ends, so that oilwill flow down into oil-pans beneath bearing-brasses fitted therein.

Two bogies are employed beneath eachvehicle, the frame of one bogiebeing connected to the frame of the other by crossed connecting-rods,each side of one bogie being connected to the opposite side of theother.

A draw-bar is made integral with or rigidly attached to the frame ofeach bogie, bymeans of which it may be steered by a similar drawbar uponthe motor or Vehicle immediately preceding it, the angularity given tothe wheels of one bogie in relation to the track being transmitted bythe crossed connectingrods to the other bogie in the opposite direction,flange friction and wear and tear of wheels in passing around shortcurves being thereby greatly diminished.

Referring to the accompanying drawings, Figure 1 is a side elevation,and Fig. 2 a plan, showing the front and rear bogies of a vehiclecoupled by crossed connecting -rods. Fig. 3 is an end elevation, andFig. 4 a plan, showing a method of fixing and staying the bolster-bea1nsto the bogie-frame; Fig. 5, an end elevation, partly in vertical centralsection Fig. 6, a transverse section on line 6 6,

Fig. 5; and Fig. 7, a transverse section on line 7 '7, Fig. 5.

Similar letters of reference indicate the same parts in all the figures.

The axle-box a surrounds the axle Z), which has a wheel fixed uponeither end, the box extending longitudinally from wheel to wheel andbeing provided with bearings c, in which the axle is journaled.

A swing link-hanger (Z is depended from each end of the axle-box a, aswing-hanger pivot e, lying in a recess formed for its reception acrossthe top of the axle-box, engaging in eyes formed in the top of the armsof the swing link-hanger upon each side of the axlebox.

The bolster-beams f are secured to the bogieframe It by bolts 2' and bystays 7c, the bogie center plate Z distributing the weight between thebolsters at the middle of the axle.

The bolstersff are located one on each side of the axle-box and areconnected at their lower edges by the cross-pieces or bolts m m, whichpass through slots in the hangers and bear upon plates 71 n, restingupon the tops of the springs 0.

The axle-box is preferably in the shape of an inverted U fitted with anoil-pan to at the bottom, which is arranged to slope toward the outerends of the axle, and feeders p are provided, through which oil may bepassed into the axle-box to lubricate the journals.

A SlODlJBQCll'ZtW-btl r is made integral with each bogie-frame, by meansof which it may be steered, and connecting-rodst connect the insidecorners of one bogie-frame to the respective opposite corners of theotherframe, so that angular movement of one bogie is transmitted to theother in the opposite di rection.

Having now particularly described and ascertained the nature of my saidinvention andin what manner the same is to be performed, I declare thatwhat I claim is- 1. In combination, the single axle and 5 wheels, theaxlebox, the swinglink-hangers depending from each end of said box, thesprings in said hangers, and the frame having bolsters upon each side ofthe axle-box with cross bearing-pieces connecting said bolsters andbearing upon thesprings, substanends connected to the bolsters, andbearing- IO tially as described. plates located between the springsandcross- 2.
